Re^3: spliting a lengthy text

I habitually run perl with -l enabled (see perlrun), which has the effect of setting $/ = "\n" (and $\ = "\n"), so print adds a newline automatically. Hence the output I posted is unmodifed.

This makes print (roughly?) equivalent to say in Perl 6.

I also seem to recall seeing a news item that suggested that this keyword would also be available in Perl 5 as of v5.10?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
